The short answer
At least 1 year from the sale, then until the buyer files a Superior Court petition to foreclose
Rhode Island runs 7 different redemption windows
Which one applies is decided by the parcel, not by the state, so read the condition before trusting the headline figure.
How the clock works
Any person entitled to notice of the sale may redeem at any time before a petition to foreclose is filed, and a private buyer cannot file that petition until one year after the sale, so the owner always has at least a year. There is no fixed outer deadline: redemption stays open until the petition is filed, and during the proceeding the court may still allow a party who files a timely answer to redeem on terms it fixes. For the first year the city or town treasurer acts as the buyer's agent to receive redemption money; after that, redemption is paid to the buyer or the buyer's agent. Shorter and longer tracks apply to abandoned or vacant property and to tax titles held by Rhode Island Housing.
Who can redeem
Only those entitled to notice of the sale under 44-9-10 and 44-9-11: the taxpayer, the present owner of record, mortgagees and mortgage assignees of record, former fee holders whose right has not been foreclosed, holders of earlier tax titles, federal agencies with recorded liens, and holders of recorded life estates and vested remainders, with their heirs and assigns.
What the owner pays to redeem
the purchase price, plus a penalty of 10 percent of the purchase price if redeemed within six months after the sale and an additional 1 percent of the purchase price for each succeeding month, plus any later taxes the buyer paid to the municipality with interest at 1 percent a month, plus the buyer's costs and the recorded-deed fee. Where the tax title was assigned by the city or town, the base is the amount stated in the assignment. After a foreclosure petition is filed, the court fixes the amount, including the costs of the proceeding and a reasonable counsel fee.
How your return accrues
The return is a statutory penalty on the purchase price, not an annual interest rate. It is 10 percent of the purchase price if the owner redeems within six months after the sale, plus 1 percent of the purchase price for each succeeding month, so 11 percent in month seven and 16 percent at twelve months. The penalty keeps rising by 1 percent a month for as long as redemption stays open, which is until a foreclosure petition is filed. On top of the penalty, the redeeming party repays any later taxes the buyer paid to the municipality with interest at 1 percent a month, the buyer's costs, and the deed recording fee the buyer paid. Once a petition is filed, redemption runs through the court on terms it fixes, including costs and a reasonable counsel fee.
What bidders actually bid down
There is no rate to bid down and no premium to bid up. Under 44-9-8 the price of every parcel is fixed at the taxes, assessments, rates, liens, interest and intervening charges due, and bidders compete by offering to take the smallest undivided part of the land for that price, never less than 1 percent. The whole parcel is sold only if no one offers to take a part. The redemption penalty is set by statute and is the same for every buyer, so a lower ownership bid does not change the return on redemption; it only shrinks the share the buyer ends up owning if the right of redemption is foreclosed. Several steps look like a sale and are not an investor sale: (1) when no bid equals the tax and charges, the collector 'purchases for the city or town' at the sale (44-9-14), which admits no investor and gives the municipality the tax title; (2) a collector's 'taking' of land for the city or town under 44-9-8.1 is not an auction; (3) a municipality's sale of its uncollected tax receivables to a bank under 44-7-25 is a financing deal, not a sale of parcels to bidders; (4) the recorded list of parcels sold (44-9-13) and the collector's deed recorded within 60 days describe a sale already held. The real investor auction is the collector's sale under 44-9-8, held by each city or town on its own date.
What happens when it ends
Unpaid city or town taxes, assessments, rates and certain municipal liens. No statute sets a minimum delinquency age: once taxes are unpaid, the collector may advertise and sell (44-9-7, 44-9-8). Before the sale the collector must post notice in two or more public places at least three weeks ahead, publish the parcel list in a local newspaper at least three weeks ahead with weekly legal notices after that, mail the taxpayer first class at least 90 days ahead and certified at least 40 days ahead, send copies to Rhode Island Housing at least 40 days ahead (a sale is void as to any parcel where that notice was not given), notify the Office of Healthy Aging for age-based abatement recipients, and notify mortgagees and other recorded parties in interest by registered or certified mail at least 20 days ahead. For owner-occupied homes of three or fewer units, Rhode Island Housing has a right of first refusal to take the tax title at the sale if it notifies the collector in time (44-9-8.3).
A redemption pays back your price plus the statutory premium, which is what makes the wait profitable; see how redemption periods work across states. If the window closes unredeemed you keep the Rhode Island tax deed, which still does not convey marketable title on its own, so budget for a quiet title action.
